+====== Packages ======
-===== Packages =====
 The code base is structured into directories. This will allow for making CP2K more modular, i.e. consisting of smaller packages with fewer dependencies. Every directory therefore contains a file named ''PACKAGE'' . A typical ''PACKAGE'', which uses python syntax, looks like this:

 The optional entry ''archive'' allows to overwrite the filename of the archive, which is created during compilation. The default name is "libcp2k<package_name>".
+====== Creating New Packages ======
+A very helpful tool for the creation of new packages is the ''plan_packages.py'' script. It takes as argument a package-plan.
+<code>
+cp2k/tools$ ./plan_packages.py ./pkg_plan.txt
+</code>
+A package-plan describes changes to the current file-layout. It can be used to assign files to new or different packages. And it can be used to change the requirements of packages. The script will outputs the dependency-violations that the changes of a package-plan would create. Hence, it provides a convenient way to analyses module dependencies and to design new packages.
